Date: Thu, 23 Sep 2021 16:28:11 +0100 From: Ross Burton <ross.burton@....com> To: linux-hardening@...r.kernel.org, linux-kernel@...r.kernel.org Cc: keescook@...omium.org Subject: [PATCH] scripts/gcc-plugins: consistently use HOSTCC The GCC plugins are built using HOSTCC, but the path to the GCC plugins headers is obtained using CC. This can lead to interesting failures if the host compiler and cross compiler are different versions, and the host compiler uses the cross headers.
